ZM1120

7.8mm numeric tube manufactured by Siemens

The ZM1120 is a red coated miniature nixie tube manufactured by Siemens. It was also manufactured by Telefunken. It is one of the smallest end view nixie tubes that ever were made. It would be perfect for projects were small space is needed (e.g. Wristwatch), but the tube is not easy to find. There is also a clear version, the ZM1122. Its very similar to the NL-7009.
